You can also bookmark individual emails for quick access through a Gmail Labs feature called ‘Quick Links’. All you have to do is go to the email you want and click on the ‘Add Quick Link’ in the Quick Links widget.

Now is the awesome part.

You can also bookmark your unread Gmail messages. Here’s how

Go to Gmail search box

Enter is:unread in:inbox for just the unread mails in your inbox

or is:unread to get all your unread emails

Hit search and bookmark the URL now

If you are on Firefox you can just drag it to the bookmark toolbar

Now, lets add a keyword by right clicking on the bookmark and go to properties.

Enter something simple like ‘unread’ or ‘gmail’ or ‘gu’

So, now anytime you want to bring up your unread emails in Gmail, just type in unread (or the keyword you used) in Firefox and voila! You can change the in: keyword to any other label you may have to bookmark a particular type of emails.
